Energy Consumption and Global Warming

After billions of years of formation, the earth is being threatened with the deleterious effects of human activities. These have done more damage in the last 50 years than throughout human history and now jeopardize the very survival of our planet's ecosphere.

Radioactive leaks from nuclear power facilities in coastal areas could be triggered by large tidal waves.
Many animals would be threatened with extinction owing to their inability to adapt to rapid climatic changes.
Unusually heavy rainfall, devastating floods and severe drought are believed to be caused by global warming.
Massive population displacement could occur in Egypt and Bangladesh, where there would be a high probability of submerging coastlines.
More droughts and expanding desertification would have a disastrous impact on food production.
Rising seawater levels (from melting glaciers and polar caps) would accelerate coastal erosion and, in certain areas, cause land to become submerged under seawater.
Reduced crop yields, especially for wheat and maize, could threaten food supply worldwide.
The habitat for disease-carrying insects would spread, increasing the chances for outbreaks of epidemics such as malaria and dengue fever.
Unable to adapt sufficiently quickly to rapid climatic changes, many plant species, too, would face extinction.
